The past two decades of research on Carbon Capture and Storage (CCS) seem to have
finally become fruitful as global leaders and energy-intensive industries are cooperating to …

The oil industry faces with crude oil emulsions formation issue. It is a common problem for
the most of oil-producing countries around the world, including the Republic of Kazakhstan …

Primary oil recovery from fractured unconventional formations, such as shale or tight sands,
is typically less than 10%. The development of an economically viable enhanced oil …

Rigorous characterizations of fluid contents, rock/fluid interactions, and pore-size
distributions are crucial in the development of unconventional resources. As a nonintrusive …

CO 2 huff-n-puff can store CO 2 and improve the recovery of tight oil reservoir. The
asphaltene precipitation produced by the interaction of CO 2 and oil causes damage to tight …

The recoverable hydrocarbon reserves of conventional oil and gas resources are very
limited in China. As important alternative resources, unconventional oil and gas have …

To date, many laboratory-based core scale (ie flooding) studies have focused on relatively
homogeneous rock samples (eg Berea sandstone) to study the migration characteristics of …

CO2 injection is an effective way to improve oil recovery for tight sandstone reservoirs. In this
study, the tight sandstone cores collected from Chang 6 Member of Yanchang Formation in …

Pore and throat blockage and wettability alteration caused by asphaltene deposition are
serious problems during the injection of CO2 into subsurface reservoirs for enhanced oil …

Blockage in reservoirs caused by asphaltene deposits and inorganic interactions is a
serious problem that may exacerbate the complexity of displacement characteristics in …
